Gland Rope

We are the leading manufacturer and supplier of gland ropes in India, providing cost-effective sealing solutions for various industrial purposes. Gland ropes, as the name might suggest, gland packings is the term normally used, although it is considerably cheaper than any mechanical seal, is a sort of rope whose purpose is wrapping around the shafts that rotate, fill the dead spaces, and leak fluid. Installing, maintaining, or repairing them requires no expertise since they are hassle-free.

How Gland Ropes Work

Gland ropes make a seal by filling the gap between rotating shafts and stationary parts, thereby controlling fluid leakage and preserving valuable process fluids. It also minimizes emissions, thereby contributing to environmental sustainability. The friction created due to the linear speed of the shaft leads to heat generation and, hence, wear and tear of the gland rope. Thus, selection of the proper gland rope material for specific working conditions is very essential for optimum performance and long service life.

Key Factors for Material Selection

The success of gland ropes relies on the material. Various materials meet different requirements of operation based on:

  • Chemical Resistance: Resistance to pH levels.
  • Pressure: The pressure in the flow system.
  • Temperature: Fluid temperature and additional heat generated by friction.
  • Shaft Speed: It is the speed of the shaft in linear meters per minute. This is considered to be another factor that may influence heat generation.

Frequently Used Gland Rope Materials

Most commonly used gland rope materials include:

  • Natural Fibres
  • Flexible Graphite
  • PTFE (Polytetrafluoroethylene)
  • Aramid Fibres
  • Carbon Fibres

Impregnation is possible with some of these with substances like PTFE or graphite to give them sliding characteristics and heat transfer properties.

People also ask

  • What is a gland rope?
  • A braided or twisted material, such as PTFE or graphite, wound around a shaft to prevent leakage.
  • How is gland rope size calculated?
  • Measure the shaft diameter and stuffing box diameter, subtract the two, and divide by two to determine the required size
  • How many types of gland ropes are there?
  • Five main types: natural fibers, graphite, PTFE, aramid, and carbon fibers.
  • How to cut gland ropes?
  • Use a sharp knife, cut slightly longer than the required length, and wrap with PTFE thread seal tape to avoid fraying.
  • How long does a gland rope last?
  • They last 1–2 years and sometimes longer under favourable conditions, proper lubrication and maintenance.
